A tension crack is not present in this verification. In the following verification problem, we examine a wedge with joints having the same dip, allowing for maximum wedging effect. These equations were later shown to be valid by laboratory tests of wedge models. The equations we will use to verify the results produced by Swedge were originally presented by Kovari and Fritz.
3Ĥ 1 Swedge Verification Problem #1 1.1 Problem Description In the first verification example, a static stability assessment (SSA) is presented to verify that Swedge computes values using the correct equations.
The results produced by Swedge agree very well with the documented examples, and confirm the reliability of Swedge results. Two wedge examples presented by Priest are also verified here.
were used to confirm the validity of a limit equilibrium analysis method presented in Kovari and Fritz. The results of these lab tests performed by Kumsar et al. The first examples presented here are based on examples and case studies presented in Kumsar, Aydan, and Ulusay. Swedge is an engineering analysis program for assessing the stability of wedges formed in rock slopes, produced by Rocscience Inc. Rockfall trajectory modelling techniques allow the calculation of vertical distribution of rocks falling from the quarry’s walls along different profiles in the area and therefore the determination of a safety perimeter from the quarry wall.1 Swedge Probabilistic analysis of the geometry and stability of surface wedges Verification Manual Rocscience Inc.Ģ Table of Contents Introduction Swedge Verification Problem # Swedge Verification Problem # Swedge Verification Problem # Swedge Verification Problem # Swedge Verification Problem # Swedge Verification Problem # Swedge Verification Problem # Referencesģ Introduction This document presents several examples, which have been used as verification problems for Swedge. Using rockmass characterization techniques, kinematic study and stability analysis, it was confirmed that many instability mechanisms are found on the walls of the quarry and cause a high risk of rockfall during the rain season, especially that the study area is inhabited. Quarries are places of high instability due to blastings, if left without rehabilitation they become sites of great risk of rockfall, which are the case of the Carian quarry, a small abandoned aggregate quarry, which turned into a slum neighborhood in the north western part of the city of Tétouan, and that has a long history of rockfall incidents since it was shut down in the 60’s.
